DISTRIBUTER-HEA'D FOR IGNITION DEVICES.

Application filed May 25, 1917.

To all whom it may concern:

Be it known that we, ALBERT E. BERDoN, CLARENCE RINGWALD, and ALBERT B. GOM- ORY, said BERDON residing at Anderson, in the countyv of Madison and State of Indiana, and said RINGWALD and GOMORY residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Distributer-Heads for Ignition Devices, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in distributer heads for ignition apparatus and has for its object the provision of a distributer head which is particularly adapted for ignition devices used on multicylinder motors where there are a considerable number of high tension cables. The distributer head is particularly well adapted for use with V type engines wherein one-half the cylinders are arranged on one side and the other cylinders on the other side of a vertical plane.

One of the objects of the present invention resides in the provision of a device which enables the cables forming the high tension leads to be readily attached to the distributer postswith a minimum of labor and material. Other objects reside in the provision of a head which is practically waterpmof, thereby minimizing the liability of the short circuits. Other objects reside in the provision of a head in which the leads may be led to their proper distributer posts irrespective of the sequence of firing order and without unduly increasing the size of the apparatus.

In the drawings: 1

Figure 1 shows in perspective a distributer head with the cap and cables in place.

Fig. 2 is a sectional View showing the interior construction, the section being taken on line 3-3 of Fig. 3 and with certain of cables detached for the sake of clearness.

Fig. 3 is a top plan view of a distributer with. the high tension cables in place and the cap removed.

The body of distributer comprises a shell 10 having integral therewith and projecting therefrom at the top and at opposite sides thereof two extensions 11. The body is divided by a horizontal wall 12 into a lower chamber 13 and an upper chamber 14. The

lower chamber is the distributer chamber and the upper chamber is the cable receivlng chamber.

Embedded in the dividing-wall 12 are L shaped distributer posts 15 and a central block 16 carrying supply contact button 17. These parts together with arotating distributer segment constitute the high tension current distributer.

Immediately above the L shaped posts 15 and extending upwardly from the upper face of the partition wall 12 are bosses 18 which are co-axially drilled and tapped as shown at 19 to receive screws 20.

There is also a boss 1S supporting the central contact block 16 which is also drilled and tapped as shown at 19 to receive a screw 20. This boss 18 is disposed above the plane of bosses 18, and serves to divide the cable receiving chamber in such a manner that the cables can be placed therein in a very compact relation whereby to insure that the cables will not be moved relatively to the chamber with the jarring of the automobile in which the distributer is used. This construction will insure that the connections of the cables with the posts will not easily be disturbed.

It will be understood that the L shaped distributer posts 15 are also tapped, whereby a good electrical connection is established between the screws 20 and the posts 15.

In the present embodiment there are nine high tension leads, but it will be understood that the number of leads depends upon the number of cylinders to which current is to be distributed. 21 is the supply lead and passes'into chamber 14 at the side of the circular shell. .22, 23, 2 1:, 25 constitute one group of leads and are admitted into chamber 14 through a number of parallel holes in one of the extensions 11. 26, 27, 28 and 29 constitute another group of leads and extend into chamber 14 through similar parallel holes in the other extension 11. Before placing the above cables in position they are pierced by an awl or similar tool. Then after they have been passed through the holes in the extensions 11 and the'shell 10, these awl holes in the cables permit the screws 20 to be forced through the cables. The screws are pointed at their lower ends as shown in Fig. 2 and these pointed ends are adapted to wedge through the insulating AND CLARENCE RINGWALD AND ALBERT B.

covering on the cables and through the stranded wires 30 therein. The screws 20 clamp the respective cable ends tightly down upon the bosses 18 and at the same time es tablish a good electrical connection between the wires 30 within the cables and the respective distributer posts 15 or central contact block 16.

The screw devices provide an exceedingly simple method of attaching the cables to the current distributing devices and obviate the necessity of employing clips and terminal devices which would, on account of the crowded condition of the cables in chamber 1e, tend to cause short circuits and jumping of the sparks to improper terminals. lhe chamber 1% being larger than chamber 13 provides ample room for crossing the cables as shown in Fig. 3. This crossing in the head is desirable in multi-oylinder engines due to the firing order in the different cylinders, and in order to lead the cables directly to their proper cylinders without twisting and crossing them outside the distributer head.

After the cables are properly attached a cap 32 is placed over the top of the chamber 1% and secured to the body of the head by screws 33. This cap completely incloses and seals the upper chamber thereby preventing the ingress of water and dirt.

The distributor head may be retained upon the ignition device in any desired manner,

is by the clips 34 shown in dotted lines in Tt will be understood that the shell 10, the extensions 11 and the dividing wall 12 are preferably molded integrally from a plastic composition such as bakelite, condensite or any of the well known phenolic condensation products. The cap may be and is preferably made from a similar material.

lt will be understood that the invention maybe modifiedin various ways which will occur to those skilled in the art. What we claim as our invention is particularly pointed out in the appended claims.
